Error when creating an image (dmg) using hdiutil

Question

Hi everybody,
I´m using a script which creates an image (dmg) from a selected folder.
This works without errors.
But I also want to create images from CDs and DVDs using this script. Doing so I always get the error "Only one image can be created at a time"
I thought that a previous imaging process was not finished yet and I rebooted the Mac. But I still get this error. Any idea?
Here is the script:
set Ordner to choose folder
tell application "Finder"
set diskNames to name of Ordner
set myNewPath to POSIX path of (path to desktop folder) as string
set theListe to every process
end tell
set myNewPath to myNewPath & diskNames & ".dmg"
set Quellordner to POSIX path of Ordner as string
set Skript to "hdiutil create -srcfolder " & Quellordner & " " & myNewPath
do shell script Skript

I believe this has something to do with terminal and have spaces in folder names / disk names. As it sees the space and thinks it is another command and in this case i believe it thinks you are trying to do two or more disk images at once. Therefore it is important to deal with spaces. Thankfully you should be ablr to get around this by using the quoted form command which i have implemented below.
I repeated your error using a folder called "Cd for Cherie". Folders without gaps such as "pH" worked fine.
I havent tested this with any disk but i believe if you alter it to this hopefully it will work
Also the name of the folder wasnt working for me so i altered to to work for me, i am using 10.4.8 so if it doesnt work for you then change it back.
--Start Code
tell application "Finder"
set infor to info for Ordner
set diskNames to name of infor
-- display dialog diskNames as string
--set diskNames to name of Ordner
set myNewPath to POSIX path of (path to desktop folder) as string
-- set theListe to every process
end tell
set myNewPath to quoted form of (myNewPath & diskNames & ".dmg")
set Quellordner to quoted form of POSIX path of Ordner as string
set Skript to "hdiutil create -srcfolder " & Quellordner & " " & myNewPath
do shell script Skript
--end code
